A pair of 1.5V lithium AA batteries designed to snap magnetically into an Xbox controller's battery bay, aimed at gamers who burn through disposable AAs faster than they'd like.
For anyone gaming often enough that disposable AAs feel like a recurring expense, yes. The 3000mWh lithium cells and magnetic mounting are built specifically around the Xbox controller's battery door, and Mupoer claims meaningfully longer runtime than typical NiMH rechargeables. There's no published customer rating on this specific listing yet, so weigh that against the otherwise strong track record of Mupoer's other AA battery products.
Rather than a generic rechargeable AA, this pack is marketed specifically for Xbox controllers, pairing 1.5V lithium cells with a magnetic mount so the batteries seat and stay put without rattling, and sizing the capacity around typical controller drain.
Mupoer rates the pack for roughly 48 hours of continuous gaming on a full charge, which the brand positions as a meaningful step up from typical NiMH AA rechargeables used in the same controllers.
The batteries are designed to snap into place magnetically, reducing the fiddling and rattling that can come with standard AA batteries in a controller's battery compartment.
Each cell is rated at 3000mWh with a steady 1.5V output — roughly 6000mWh combined per pair — which Mupoer says delivers at least 50% longer battery life than comparable NiMH AAs in the same use case.
Beyond controllers, Mupoer lists these as compatible with toys and devices like Blink cameras, so the pack isn't locked to gaming use only.

This isn't a general-purpose AA battery — it's built around one job: keeping an Xbox controller running longer between charges. If that's your use case, the magnetic fit and rated runtime make it a reasonable buy, though the lack of public reviews on this exact listing means you're an early adopter.
